'This invention relates to valve or faucet de- Vices and has for one of its objects the provision of an organization in which the constituent elements are so coordinated structurally and funotionally as to secure improved results with inexpensive material which may always remain in effective working condition, there being no renewable parts, such as leak-proof gaskets or packings, in the structure.

The valve controls movement of liquid, such as water, gas, or steam, in a pipe or conduit, and as it is often desirable to know the position of the valve relative to its seat or opening, at a glance the present structure .includes a dial or l5 graduated valve-opening indicating index means,

under operative control of the valve manipulating means to exteriorly show the position of the inner or closure parts of the valve. With this index means the operative position of the valve is quickly apprehended, without touching the valve. f A

This latter feature is particularly useful in the supervision of .a number of installed. valves wherein the positions of said valves may be visually checked as to their proper settings.

Since the cut-off valve or closure portion is disposed in the valve passage of in the path of movement ofthe fluid; and is also movable into or out of the said path, a further important object of the invention is to so construct the eutoff valve that, during its movement, the liquid pressures may be effective, to seal the valve, when closed. As shall hereinafter appear, the cut-off valve portions comprise spaced segments, which 35 are relatively expansible, and the fluid pressure acts to expand the segments to seat them against leakage.

As the fluid moves under pressure, and as it is desirable to present a large surface oi the inner 40 portions of the segments to the moving fluid, a

still further object of the invention is to so con.- struct the said surfaces as to present a maximum of sealing area to the action of the iiuid pressure.

A further object is to provide the valve seat and cut-off or valve portions with coacting edges and ledges, soI that when the duct is closed by the valve cut-ofi, it is rmly pressed against the said ledge portions. 0 A further object is to provide the valve cut-ofi with a seat cleaning means, whereby closing the valve will clear the seat portion of all particles which tend to prevent proper closure, and which when the valve is opened will permit such parti- 5 cles to be carried away by the passing fluid stream.

Other objects and advantages will hereinafter appear.

.Similar characters of reference designate corresponding parts throughout the several views.

The device includes an outer composite casing, including a base portion i0, the opposite openings i, 92,01 which form a duct or passage, and are threaded to receive any threaded pipe or conduit connections. Disposed in these ducts, which form the passageway of the line, is a partition i3 which directs the fluid downwardly to the valve opening, and against the inner cylindrical face of which partition a relatively movable valve guide segment iii carried by the movable base valve assembly l5, is slidable, best shown in Fig. 2. This section includes a port closing valve segment It, which is preferably resiliently disposed opposite said rst guide segment. The casing portion l0 forms a section of the pipe line.

Cooperating with the axially :movable valve body extension l5 is a revolvable top section, Fig. 2, which includes a hand wheel li and a threaded stem portion i8. Turning movement oi. the hand wheel moves the valve section l5 between open and closed positions, shown in l and 2, there being on said section opposed pairs of integral guiding flange projections HS, 2Q, which are movable along guide ribs 2l, 22 which are integral with the body extension 23.

This latter extension, which includes an integral seating flange 24, finds a seat on the lower casing or base and as said base has therein a vsuitable aperture to receive a dowel pin 26 located in flange 24, the structures are registered and held against turning movement while the hand wheel is revolved. The inner faces of the body forming portions 23 and 25 are disposed in flush relation, and are coupled in uid tight assembly by an internally threaded coupling nut or union 2l, which is hexed to permit the use of a wrench, and engages with suitable threads on the lower casing portion 25.

It will be noted, by referring to Fig. 2, that the valve segments H4 and i6 are provided at their lower edges with a relief channel thus leaving clean edges it and lll', Figs. 2, 9 and l2. These edges cooperate with vthe lower stop seat or valve abutting shoulder Llil located at the terminus of the valve stroke in the body portion This abutting shoulder or ledge iil is truly machined as are also of the valve segments valve is closed, the said edges said seat or ledge 'its' in a 'fluid tight manner and thus, especially as to valve segment l5, prevent leakage through the port when the valve is closed.

During the closing movement of the valve the segments lll-l5, by reason oi the champfered lower edges (L -l1, Figs. 1, 2, 9 and l2, tend to scrape the cylindrical faces lll clear of deposited material, and thus `carry all such material down into the channel formed between the edges a and 4l! and the edges lll and The material is thus removed by the flowing fluid stream when the valve is opened and thus the active valve faces or seats, as lil', which cooperate with the lace or seat 4| of the segment l'a and the corresponding face of the segment M, are kept clean.

The stem i8 has thereon an annular shoulder 28, the tapered face 29 oi which nds a seat on a correspondingly tapered seat 29' o the casing extension 2S; and a spring 3B, terminally seated between the threaded support collar 3l and the shoulder 28, presses the latter upwardly, said surfaces are held in rotatable, liquid tight relation. The collar 3l, which is provided with apertures, as at 32, to receive a spanner wrench, is held by the threaded bore. 3l in said extension In order to quie/lily and visually ascertain, from the exterior, the extent to which the valve is open or closed, the body extension 23 is provided with indicia 33, in the present instance shown as graduation marks, figures, and the words on and oi The hand wheel is provided with a keyed or internally threaded cylindrical. collar Elfi, which engages th-e external threads of a recipll-l(5, so that when the press rmly on rocable index collar 35, and as the latter, as well as the neck 3S of the portion 23, are provided with associate flatted portions 3l, Figs. 5 and 6, said index collar is slidably movable to cooperate with the aforesaid indicating marks, as is clearly visible from an inspection of Figs. 1 and 2. The hand wheel is retained on a terminally threaded angular tang i of the stein by a nut 39, as in Fig. 2.

Pressure of water or Huid in the line acts against the inner fac-es oli both segments and tightly hold the outer face of the cut-ol segment l5, against the cylindrical face it of the valve duct casing itl, in any position of the valve. As said segment it has the lower flange 4U, which is provided with inclined surface, as shown, this provides an enlarged area against which the fluid pressure in the line, exerts a pressure to hold the valve structure securely expanded against the inner' face of the casing 25.

The reversely facing portion of the valve seg ment it is structurally, like that of the port cutoff segment l. The segment l? has a bore 42, Figs. 2 and 9, and in the latter is slidably disposed a bushing [i3 of the segment ll. A spring ifi between the opposed valve segments gives the segments an initial expanding movement, but the reaction of the spring is so arranged as to permit axial sliding movement of the segments, during rotation or the valve stern. Said bushing andvalve segment portions may have therein pressure equalizirg registering openings as at d5, 45, to allow fluid pressures to be exerted above in the chamber oi extension l5, as well as below the valve cut-ofi segments.

The valve is constructed of rust proof material; and no packings or gaskets are used, so that the device may last indefinitely without renewal of parts.

What claim is:

A valve comprising a casing having a longitudi-V nal passage and a lateral passage; a partition between the lateral passage and one end of the longitudinal passage and provided with a vertical wall and a bottom wall having a lower opening and a horizontal seat surrounding the opening; a vertical seat between said lateral passage and the other end of the longitudinal passageya movable element havin valve segments respectively conformably yieldably engageable with said vertical wall and vertical seat and each having a lower edge accurately tting said horizontal seat; and means for sliding said element and segments away from said seats.
